A sterile implantable device intended to support, contour, and provide structure for the craniofacial anatomy (i.e., head and face including the chin, cheeks, nose, eye sockets and ears) during reconstructive and plastic surgery procedures. It is typically a high-density polyethylene (PE) material with an interconnecting pore structure that supports tissue ingrowth. The device is available in blocks, sheets, wedges and spheres that can be cut by the surgeon to meet the patient's specific needs. This is a single-use device.
